Loading examples via URL, the address should stays

[grzanka]

I load an example via URL, i.e. using following link:

https://yaptide.github.io/web_dev?https://gist.githubusercontent.com/grzanka/f9314302d127836b2e7b3ec76379633d/raw/62eae84905ae452d84017fa8675985c5bfe432d3/plan1.json

it loads correctly, but the address in the browser changes to:
https://yaptide.github.io/web_dev
after example is loaded.

The address should be still the same, even if I made any modification of the objects in the editor or if I submit new runs.
